Optima Express 8.5.0 - 8.7.5 - Unauthenticated Author Account Creation & Application Password Rotation via ihf_clear_cache

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The Optima Express IDX WordPress plugin before 8.7.6 does not perform any authorisation check on one of its AJAX actions that is available to logged-out users, allowing unauthenticated attackers to force the creation of a fixed author-role account and to repeatedly rotate its application password on any connected install.
